Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 459195

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: bpf: fix end-of-list detection in
 cgroup_storage_get_next_key() list_next_entry() never returns NULL -- when the current element is the last
 entry it wraps to the list head via container_of(). The subsequent NULL check is therefore dead code and
 get_next_key() never returns -ENOENT for the last element, instead reading storage->key from a bogus
 pointer that aliases internal map fields and copying the result to userspace. Replace it with
 list_entry_is_head() so the function correctly returns -ENOENT when there are no more entries.
 (CVE-2026-45838)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
